Originální popis anglicky:
wcsstr - locate a substring in a wide-character string
Návod, kniha: Linux Programmer's Manual
#include <wchar.h>
wchar_t *wcsstr(const wchar_t *haystack, const wchar_t *needle);
The
wcsstr function is the wide-character equivalent of the
strstr
function. It searches for the first occurrence of the wide-character string
needle (without its terminating L'\0' character) as a substring in the
wide-character string
haystack.
The
wcsstr function returns a pointer to the first occurrence of
needle in
haystack. It returns NULL if
needle does not
occur as a substring in
haystack.
Note the special case: If
needle is the empty wide-character string, the
return value is always
haystack itself.
ISO/ANSI C, UNIX98
